Good news for Java developers: Temurin JDK 25 for x64 Windows is now available in the Red Hat Customer Portal, giving you another supported, production‑ready option for running Java on Windows.
A few things to know
Red Hat has long offered commercial support for Temurin builds, and with this release Temurin is now accessible directly through the Red Hat Customer Portal. There will not be a Red Hat build of OpenJDK for JDK 25 on 64‑bit Windows, so Temurin is the primary option for this platform.
Why this matters for developers
You can pick the enterprise distribution that best fits your support needs without changing the code you build on. This flexibility is helpful when teams want to standardize tooling while keeping options for support, service-level agreements (SLAs), or AI‑focused services.
The Red Hat engineering team aligned the compiler versions and options so Temurin behaves like the Red Hat build of OpenJDK. Red Hat verified the builds are reproducible—Temurin and RHBO binaries are byte‑for‑byte identical except for vendor metadata—so switching between them causes fewer surprises.
The Red Hat product security team independently reproduces and validates Temurin builds on trusted infrastructure. Temurin is AQAvit verified and TCK certified, and Red Hat has independently attested to reproducibility. This verification provides additional confidence for production use.
What to expect next
Red Hat will keep contributing to and verifying Temurin at the Eclipse Adoptium project, and we'll share more details as the formal Reproducible Attestation program rolls out. In the meantime, developers get a supported, vetted JDK option in the Red Hat Customer Portal—more flexibility for modern Java applications with the assurances teams need for production
